Matt Damon has revealed that he broke his collarbone while mountain biking.
The 'Monuments Men' star told Jay Leno that he snapped his clavicle after his bike got stuck on a bunch of rocks while he was riding down a hill and he tumbled over the handlebars.
According to the Hollywood Reporter, Damon added that he is not a very good mountain biker, and he just hit a pile of rocks, and that he kept going on even though the bike had stopped.
